12 Functional Descriptions
12.28.8 Overview of function identifiers and configuring parameters (DB 2, DR 2 ... DR 6)
Axial feed:
Formula for servo trace:
Formula for high-speed data channel:
Example: G91 G94 F1000 Z10 X10
In servo trace:
Read-off MW=
with LF =
and IT =
results in RW =
i.e. RW =
The same feedrate results in the X axis. Both together have therefore a path feedrate of SQRT
2 2
( 707 + 707 ) = 1000 [mm/min] as programmed.
Note: "Channel/IKA no." is not relevant in the servo trace screen!
Path feedrate:
Formula for servo trace:
Formula for high-speed data channel:
Example: G91 G94 F1000 Z10 X10
In servo trace:
Read-off MW=
with EF =
and IT =
results in RW =
i.e. RW =
Distance to go on path:
Formula for servo trace:
Formula for high-speed data channel:
IKA input quantity value A:
Important: The IKA No. selected in the servo trace screen must be larger by 1 than the
desired IKA No (applies for SW 5.1 and 5.2).
If the input quantity is a position, the following applies:
Formula for servo trace
Formula for high-speed data channel:
If the input quantity is an R parameter, the following applies:
